' 210mm (01. sea-s7) This invention relates to packagesand the object is to provide a sightly'. and inexpensive package in which the outer layer of the wrapping is of transparent cellulosic material 'suchasrthat popularly known by the name "Cellophane although that word more properly denotes a.par-' ticular manufacture of such material. .My invention flndsa particular.,-application*to the go ofsoap in elevation and spaced therefrom and in section the'various wrappings; Fig. 3 is -a perspective illustrating the. wrapping partly completed; and a Y Fig. 4- is a perspective showing a later stage of. the wrapping. r It willbe understood that in the the thickness of various layers or wrapping material is necessarily exaggerated. v at the present time the purchasing public so favors articles enclosed in an'outer wrapping of what is known to it as qellophanefl Such a package may be provided by enclosing a package ofconventional or pre-existing form in a Cellophane wrapper but at ,a correspondingly increased cost for material and handling. The

. present inventionprovides for an equally attrac-- tive package at a lesser cost. Moreover, in the case of soap, for example, particularly. stringent conditions must be met. .Toiletisoap at the pres- 49 ent time is commonly packaged in a fresh or.

' green state and itis desirable to maintainthe shapely form of the cake; without drying or warping until it reaches the hands of the consumer. Due to themoisturecontent the cake of soap may sweat and may aflect the printingof the enclosing wrapping or otherwise damage the wrapping in such a way as to a'flect its appearance and detract from salability. These conditions, among others, are met by the' construction which I am about to describe.

- Referring to the annexed drawing, the cake 5 of soap is enclosed .in a wrapping which comprises an outersheet I' of transparent cellulosic material desirably of the so -called moistureproof type, that is, one which has a coating of a suitable nitro-cellulose lacquer which usually embodies a wax-like plesticizer. I have not attempted in the drawingv to show this lacquer coating. On the interior side of the transparent sheet I there is printed a suitable imagein reverse constituted by alaye'r. 9 of pigment or ink. showninFlg. 2 but omitted for clearness in the other figures, and in which may be embodied a.v

suitable design such as a medallion l I, illustrated in Figs. 1 and 4, and lettering as It. The print- 1, ing is of such an extentthat when the sheet is applied about the. soap cake or other commodity it conceals the same and the appearanceof the transparent layer! with the pigment layer 9 onthe interior thereofwhen it is in position is that .15 of an innerprinted wrapping paper or the like, which, however; is merely the layer of ink, en closed by the transparent cellulose. It-may be noted here that I use the word "pigment toreferto colored material applied as an ink or paint 20 and donot necessarily imply a pigment in the more technical sense of a dry'powder suspended in a vehicle to form a paint.

If the printed cellulosic sheet were wrapped alone about a cake of soap, it will. beapparent 25 that at the Joints where sealing is required the pigment layer would be presentedin opposition to the outer surface. The-adhesives commonly used for transparent cellulose have'a solvent I action thereonand would attackthe ink,'especially since lacquer base ink is customarilyused, and thus spoilthe appearance of the package. Moreover, the adhesion of the ink or pigment layer tov transparent cellulose is comparatively weak and. if the. printing is on so-called mois- 5 t'ure-proof material, the adherence can-be-nobetter than that of thelacquer layer over which itis applied. It is therefore desirable to. provide a joint which, while secure. willseparate with-- out breakine away the pigment layer to give an unsightly appearance to the wrapper when removed, which would be likely suggest dam ageto thepm'chaser.

In accordance with my invention I .9.

thermoplastic adhesive positioned inwardly of 5' the ink layer at least at the location of the Joints to form aseal by its adherence on the onehand to the pigment layer and on the other the outer faceof-the cellulosic sheet. Parana wax of the kind .used'in the manufactureiofgc self-sealing: waxed papers, such as bread wrappers, is an example of such Oonveniently'I may provide a layer of wax completely covering the inner face of the pigment layer and serving completely to protect it fromthe soap.

-Asillustratedin To obtain expeditiously and economically the advantages of a substantially unitary wrapping capable of application by a single wrapping operation the wax in the preferred embodiment of the invention herein illustrated is supported on a carrier sheet l3. A complete inner layer of wax is provided by the use of a sheet of ordinary waxed paper of the so-called self-sealing variety embodying a paper base. which may be of fairly cheap quality, coated throughout its area with' matic character the layers of this pleated portion are showmseparated for clearness, but it will be understood that inpractice they lie close together and ordinarily will be joined together by the coherence ofthewax making a'stifi central band of approximately the length of the soap cake 5.

Figs. 3 and 4, the cellulosic outer sheet 'I and the inner waxed sheet ii are wrapped as one about the soap cake 5. In Fig. 8 this wrapping is shown partially completed as if the work were being done by hand. Ordinarily a machine would be used and it will be noted that the two sheets could be applied by a single wrapping unit; As the result of this application" of the superposed sheets as a unit they are'interleaved 'at the Joints of the package Thus at the. longitudinal joint about to be completed across the" broad face of the cake-by folding down the upstanding portion 'shown'in Fig. 3 there will be provided serially from the upper'face of the cake as there-shown nrst the waxed paper layer It and then the cellulosic layer I as shown in the folded-down "position, next a waxed paper layer and finally a cellulosic layer. Similarly at illustrated in Fig. 4, if the lower flap is first folded upwardly, the. waxed layer It will be next to the soap cake, then the celiulosic layer 5, then the waxed layer l3 and then the cellulosiclayerl. Asaresult ofthisitwillbeseen that the outer surface of the underlying portion of the celiulosic layer I which iscoated with lacquer will be presented at the jointto the waxed paper layer. are

the end joints, as

adapted to cohe:e onslight heating to eflect sealing of the package without the use of adhesives possibly deleterious to the ink.

In the package described the soap receives a double protection both from the'waxed paper inner wrapping and from the outer wrapping.

The dress of the package, such as' the coloring, decoration, trade-marks and the like, is provided by the layer of ink adherent to the inner face of the transparent cellulose sheet I. This ink is completely protected from the soap and vice versa by the intervening waxed paper. The waxed paper which isrelatively unsightly on the other'hand is completely covered by the layer of ink.- The exterior appearance of the. package is that of a commodity in'an attractively printed paper wrapper enclosed by an extemal wrapping of transparent cellulose. The

package may be formed in a single simple wrapping operation and with economy of materials.

I am aware-that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing'description to indicate the scope of the invention. I

I claim:

1. A package comprising acommodity, an en-' closing wrapping therefor comprising an outer sheet of transparent cellulosic material and a pigment layer over substantially the entire inner face thereof to simulate an interior enclosed wrapp g of like waxed paper'having a central relatively stiff zone to provide an encircling band about the commodity defining the shape of the enclosing wrapping, the two sheets being folded as one about the body and sealed by the coherence of the 'wax and the outer face of the-wrapping.

2. A package closing wrapping. therefor comprising an outer sheet of transparent ner face thereof to simulate an interior enclosed wrappin of like color and an inner sheet of waxed paper having a central portion pleated to provide a multiple thickness to provide an.

'. encircling bandabout the commodity defining the shape of the enclosing wrapping. the two sheets beingfolded as one-about the sededby h m ofthewaxandthe outerfacc of the wrapping. v
